我正在尝试网络服务器和客户端..(混合应用程序!使用cordova)但Access-Control-Allow-Origin错误..所以我下载了chrome扩展程序cors ..但是没有工作..
[server.js]
var app = require('express')();
var http = require('http').Server(app);
var cors = require('cors');
var io = require('socket.io')(http);
// io.set('origins','*:*');
io.on('connection', function(socket){
console.log('a user connected');
socket.on('weather_location', function(msg){
socket.emit('message', msg);
})
});
http.listen(80, function(){
console.log('listening on *:3737');
});
[index.html的]
